Graph those points given, in a cartesian plane grid,
that is, an x,y axis grid

and try to make a straight line from the leftmost, to
the rightmost, they don't really line up as a straight
line, so... try to draw a line that will cover "most of
the points", there will be a couple or so "outliers",
the line that "covers most of the points" is so-called
"best-fit" line, so, using that line, try to get what
"y" is, when x = 3

Answer:

Step-by-step explanation:

Because the only step is to subtract 9 from both sides and then you get x=12

A fair coin is tossed three times and the events A, B, and C are defined as follows: A:{ At least one head is observed } B:{ At

kicyunya [14]

Answer:

(a) 1/2

(b) 1/2

(c) 1/8

Step-by-step explanation:

Since, when a fair coin is tossed three times,

The the total number of possible outcomes

n(S) = 2 × 2 × 2

= 8 { HHH, HHT, HTH, THH, HTT, THT, TTH, TTT },

Here, B : { At least two heads are observed } ,

⇒ B = {HHH, HHT, HTH, THH},

⇒ n(B) = 4,

Since,

$\text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}$

(a) So, the probability of B,

$P(B) =\frac{n(B)}{n(S)}=\frac{4}{8}=\frac{1}{2}$

(b) A : { At least one head is observed },

⇒ A = {HHH, HHT, HTH, THH, HTT, THT, TTH},

∵ A ∩ B = {HHH, HHT, HTH, THH},

n(A∩ B) = 4,

$\implies P(A\cap B) = \frac{n(A\cap B)}{n(S)} = \frac{4}{8}=\frac{1}{2}$

(c) C: { The number of heads observed is odd },

⇒ C = { HHH, HTT, THT, TTH},

∵ A ∩ B ∩ C = {HHH},

⇒ n(A ∩ B ∩ C) = 1,

$\implies P(A\cap B\cap C)=\frac{1}{8}$

Mark just received word that he scored 88% on a trigonometry test. Mark is also in an advanced algebra course. Is Mark's score o

katen-ka-za [31]

First off, it would not be C because there are no guidelines to score too high on a test
Then, D would also be wrong because since he scored high, it doesn't just mean that the test was easy.
Now it comes to the yes or no between A and B, since he is just one of the many students in Trigonometry, it cant be a very accurate representation therefore the answer to the problem would be A
Solution: A. No, because Mark is not representative of the population of the trigonometry class

Find the equation of this line. A y = [?] + [ 1 Enter D

VMariaS [17]

The equation of this line is given by:

y = -1/2x + 1.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.

b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Given two points, the slope is given by <u>change in y divided by change in x</u>. In this problem, we have points (0,1) and (2,0), hence:

m = (1 - 0)/(0 - 2) = -1/2.

Point (0,1) also means that the y-intercept is of b = 1, hence the equation of this line is given by:

y = -1/2x + 1.

Given triangle fge find m hfe if m g = 65

Natali5045456 [20]

What is the first point I cant even see it? but all triangles equal 180 degrees so It's B becuase mg and me are 65 degrees 65+65 equals 130. 130 plus 50 is 180 thus your answer I hope I could help <span>(o^▽^o) <3</span>
